| The patient's medical record, containing the reasons for hospitalization,
clinical evolution, laboratory tests, prescription drugs and other relevant
information is of utmost importance to medical management care. Information
technology plays a key role in communicating and disseminating the patient's
clinical data [1]. The Sana Mobile, originally developed by MIT (the
Massachusetts Institute of Technology) for mobile platform, consists of an open
source electronic medical record. It has revolutionized the delivery of
healthcare services in remote areas in a clear and objective way [2]. The
mobile device stores Sana medical data, text files, audio and video containing
patient's clinical information while transmitting data over the mobile platform
to a web server, the Open Medical Record System -- OpenMRS. This system gathers
information about medications, diagnoses, and others crucial data from a
patient, making them available to consultations by many medical experts.
Our tests with Sana Mobile -- OpenMRS focus on the development of an experimental extension of this mobile platform and its use in supporting education and training of medical students encompassing routine free ambulatory care and multidisciplinary research project. Participating in this study are researches and students of Software Engineering, Medicine and Design, respectively Software Engineering Lab -- LES of the Department of Informatics of the Pontifical Catholic University of Rio de Janeiro -- PUC-Rio, the School of Medicine and Surgery of the State University of Rio de Janeiro -- UNIRIO which includes Gaffrée and Guinle University Hospital -- HUGG, Laboratory of Ergonomics and Usability -- LEUI of the Department of Arts and Design at PUC-Rio, under the coordination of LES.

| Cross Cultural Design Considerations in HealthCare | | BIBAK | Full-Text | 13-19 | |
| Joyram Chakraborty | |||
| Increasing number of health care providers are leveraging the power of
technology to provide access to medical practitioners and patients on a global
scale. However, there is limited research in the area of cross cultural design
of the tools being used. This paper presents a work-in-progress in the area of
cross cultural design of health care tools. The main interest is to outline
some of the cross cultural challenges of designing and implementing healthcare
tools on a global scale and some possible solutions. Keywords: Healthcare; Cross-Cultural; User Experience; Usability | |||
| Designing Copresent Cycling Experience | | BIBA | Full-Text | 20-25 | |
| Yun-Maw Cheng; Wei-Ju Chen; Tong-Ying Wu; Frode Eika Sandnes; Chris Johnson; Chao-Yang Yang | |||
| There has been much UbiComp research into motivating people to live more active and healthy lifestyle with sports. The idea behind these approaches is centered on social and peer effects in enhancing exercise adherence. While research of this kind has been prolific, there has very little work been done to identify factors that embody comfortable and informed accompanied exercise experience. This paper takes an increasingly attractive cycling theme as a testbed and proposes an unobtrusive and intuitive interface arrangement based on light. It can create a sense of being together with each other for distant apart cyclists. The initial results yield a good level of comprehension and motivation towards the use of the interface. The hope is that the elicited recommendations can guide the design of UbiComp technologies for social motivational physical exercises. | |||
| Achieving Electronic Health Record Access from the Cloud | | BIBAK | Full-Text | 26-35 | |
| Brian Coats; Subrata Acharya | |||
| There is an impending requirement for healthcare providers to enable
widespread access to their electronic health record systems for the patients
they serve. Programs such as the Department of Health and Human Services'
Meaningful Use are providing monetary incentives to providers for offering this
type of access but affording virtually no guidance as to how it could be
accomplished. This research proposes a solution to this challenge by creating a
flexible, proven framework that sets the stage for ubiquitous patient access to
electronic health records, while preserving security and privacy. Using
technologies such as OpenID and federated authentication, this research
establishes a standardized approach for healthcare providers to follow to
bridge their EHR systems to the Cloud and offer the type of pervasive
electronic access the connected world demands. Keywords: Healthcare Information Security; Identity Assurance; OpenID; Portable

| Two case studies of the development of Smartphone self-reporting mHealth
applications are described: a wellness diary for asthma management combined
with Bluetooth pulse oximeter and manual peak flow measurements; and a
questionnaire for ecological assessment of distress during fertility treatment.
Results are presented of user experiences with the self-reporting application
and the capture of physiological measurements in the case of the asthma diary
project and the findings from a phone audit at an early stage of design in the
case of the in vitro fertilisation (IVF) study. Issues raised by ethics
committees are also discussed. It is concluded that the optimal adoption of
Smartphone self-reporting applications will require a good appreciation of user
and ethics panel requirements at an early stage in their development, so that
the correct design choices can be made. Keywords: mHealth; Self-monitoring; Adherence; User experience; Consumer and User;

| Electronic Health Records: A Case Study of an Implementation | | BIBAK | Full-Text | 46-55 | |
| Guillaume Cusseau; Jon Grinsell; Christopher Wenzel; Fan Zhao | |||
| Since healthcare institutions have to manage efficiently many terabytes of
data on their patients, they need tools that allow them to have an easy access
to their data and that enable them to share their data with every specialist
involved in the treatment of a patient. That's why they increasingly adopt EMR
and EHR systems. As they are quite recent systems, healthcare institutions
usually lack of experience to implement these systems. The purpose of this
paper is to do a case study on the implementation of an EHR system in a local
healthcare institution, and then to analyze this case study to give directions
so as to avoid some arising issues. Keywords: EHR; EMR; Implementation; Case Study | |||
| Healthcare Interoperability: CDA Documents Consolidation Using Transport Record Summary (TRS) Construction | | BIBAK | Full-Text | 56-65 | |
| Philip DePalo; Kyung Eun Park; Yeong-Tae Song | |||
| Thanks to recent medical record standards and distributed technology, the
exchange of medical documents has become readily available. Healthcare
institutions are able to share documents with other providers; however,
patients who require medical transport are still subject to rudimentary
exchange of information through verbal reports and outdated hand written
medical notes. An ongoing exchange of medical documents between patient
transport units and the facilities they serve would help reduce medical errors.
Our approach searches for available documents that are relevant to the
patients' current conditions based on medical coding within these documents,
clinical document architecture (CDA) documents, using HL7 message exchange
mechanism in SOAP envelopes. These CDA documents are then consolidated into a
single transport record summary (TRS) document to filter out redundancies and
provide destination medical service provider with the most pertinent
information that is readily accessible to both human and machine. In a time
critical environment, access to multiple documents from difference sources is
not likely feasible. For this reason, we proposes a CDA document consolidation
tool, the TRS Constructor, which creates a TRS by querying and analyzing
patient's multiple CDA documents. The new TRS will be registered into the
Health Information Exchange (HIE) environment for cross-reference across
healthcare facilities and other providers. Keywords: Enterprise architecture; electronic health records (EHR); electronic health

| Designing, Implementing and Testing a Mobile Application to Assist with Pediatric-to-Adult Health Care Transition | | BIBAK | Full-Text | 66-75 | |
| Jeremy Dixon; Josh Dehlinger; Shannan DeLany Dixon | |||
| As development of mobile applications continues to expand, accessibility and
utility for users who are differently-abled will become essential. One aspect
that impacts a large portion of the differently-abled population is the process
of medical transition. Medical transition for patients with chronic diseases
from pediatric-based care to adult-based care is one that has been studied,
developed and implemented for a number of years; recently, it has become a top
priority in healthcare. Due to the complexities of the transition process, a
well-designed, intuitive mobile application may improve the standardization and
ease of care for these patients. This paper proposes and analyzes the design
for a mobile transition navigator application (MTNA) while taking into account
some of the most common considerations when working with differently-abled
users. Specifically, three aspects of mobile application design are examined:
(1) mobile user interfaces are different than traditional interfaces; 2. a
variety of mobile platforms exist; and, 3. mobile platforms generate benefits
and concerns such as the wide variety of screen sizes and resolutions. Keywords: mobile applications; differently-abled technologies; human-computer

| Study on Relationship between Foot Pressure Pattern and Hallux Valgus (HV) Progression | | BIBAK | Full-Text | 76-83 | |

| Hallux valgus is one of the most common foot deformities. Plantar pressure
technologies are used widely for determination of biomechanical changes in foot
during walking. There are already published claims relating to the pressure
distribution of HV condition. However some of these claims are disputed and
challenged. Although, disputed or otherwise, association of HV to sole pressure
widely presented as a means of identifying such condition. Or knowing that HV
exist, establishing what kind of pressure variation is expected may lead to
better foot wear design for HV patients. Despite of extensive work on sole
pressure patterns of patients, there has been no reported work found on
conditions which leads to HV. Considering the fact that 23% of adults develop
such condition during their life time, understanding HV is badly needed.
To have better understanding of how plantar pressure patterns can be linked to the deformity progression or existence, extracting some patterns out of force and pressure measurements can be beneficial in recognising the patients with and without deformity during their gait cycle. We examined the dynamic changes of the forces that applied to the whole sole of the feet in control group and in the patients group when they walked at different speeds. It was observed for those with HV condition having higher forces on 2nd and 3rd metatarsal heads, and less force on the 1st metatarsal head compared to those without the condition. Although this finding was previously reported in the literature what was new was the fact that, speed of walking shown to have a significant influences on plantar force distribution. This finding in itself is significant as no sole pressure distribution given in conjunction with walking speed in the past. It was observed that there was significant variability of pressure distribution of the same individual from one trial to another indicating that getting consistent pressure pattern is an important hurdle to overcome. After many trials individuals' walking regulated giving consistent readings. After achieving this, it was further discovered that pressure pattern very much depended on walking speed. Considering the fact that inconsistency of pressure of unregulated (casual) walking and variability of due to speed raises doubts of validity of previously published work on HV which ignored such factors. Having said that, in our studies too, raised loading is observed on Metatarsal 2 and, 3 although it was not possible to give statistical significance to these finding. Although the loading on metatarsal 2 and 3 may indicate existence of HV, in authors' opinion, there is little chance of using pressure pattern as a predictive tool as no such pressure increase observed on those appeared to be at the start of HV condition or any individual with normal feet.

| A Server-Based System Supporting Motor Learning through Real-Time and Reflective Learning Activities | | BIBAK | Full-Text | 84-93 | |
| Naka Gotoda; Yoshihisa Sakurai; Kenji Matsuura; Koji Nakagawa; Chikara Miyaji | |||
| This paper describes a design of training-diary system intended for motor
learning regarding daily outdoor activities including sports. As for motor
skill, both monitoring and advising based on the key points which are hard to
obtain, are significant factors for improving such motor skills. The points
comprise the timing of advice and content. Therefore, we propose a system which
automatically generates coaching materials based on real-time monitoring data.
It aims to become helpful in finding out such points. During training, the
server provides learners and the coaches with an annotation on timeline
messages of a mobile-device application by adjustable
biomechanical/physiological threshold parameters while receiving the data via
the mobile device with wireless sensors. After training, s/he can reflect the
reconstructed annotations as diary for next training. Thus, the learners can
discuss the key points with the coaches through a trial and error process
concerning the threshold adjustment. Keywords: Bio-feedback; remote coaching; wireless sensor; annotation; content

| Usability Evaluation of a Voluntary Patient Safety Reporting System: Understanding the Difference between Predicted and Observed Time Values by Retrospective Think-Aloud Protocols | | BIBAK | Full-Text | 94-100 | |
| Lei Hua; Yang Gong | |||
| The study evaluated the usability of a voluntary patient safety reporting
system using two established methods of cognitive task analysis and
retrospective think-aloud protocols. Two usability experts and ten end users
were employed in two separated experiments, and predicted and observed task
execution times were obtained for comparison purpose. According to the results,
mental operations contributed to the major effort in reporting. The significant
time differences were identified that pointed out the difficulty in human
cognition as users interacted with the system. At last, the data collected by
retrospective think-aloud technique, e.g. the response consistency on
structured questions and the user's attitudes, revealed the frequent usability
problems impeding completion of a quality report. Keywords: patient safety; voluntary reporting; cognitive task analysis; retrospective

| Usability in RFP's: The Current Practice and Outline for the Future | | BIBAK | Full-Text | 101-106 | |
| Timo Jokela; Juha Laine; Marko Nieminen | |||
| Studies show that healthcare and other government systems suffer from poor
usability. In this research, we aim to understand the reasons and propose
solutions to this problem. We conclude so far that (1) the critical phase where
to address usability in government system development contracting is request
for proposals (RFP), (2) the appropriate place for usability in a RFP is
requirements rather than selection criteria and (3) usability requirements
should based on user performance, rather than on design principles, usability
guidelines, process requirements, or such. We find that defining user
performance based usability requirements is a challenging task and a most
relevant subject for further research. Keywords: Usability; government systems; RFP; request for proposals; usability

| Design and Interface Considerations for Web-Enabled Data Management in Civil Infrastructure Health Monitoring | | BIBA | Full-Text | 107-116 | |
| David E. Kosnik; Lawrence J. Henschen | |||
| We present principles and techniques for design of Web-enabled data aggregation, storage, and visualization software for structural health monitoring of civil infrastructure: the process of collecting and analyzing sensor data related to the condition or behavior of constructed facilities (e.g., bridges, dams, tunnels) to promote safe and efficient service at a reasonable cost. Due to widely variable user requirements and the vast range of data types and display methods required, good human-computer interfaces for engineering applications are still difficult to design and implement, and continue to be constructed in more-or-less ad hoc manners. We approach human-computer interaction in the civil engineering domain through common HCI methods, such as user interviews, use case design and analysis, representation in UML, and so on. However, this paper is focused on two special techniques that are not commonly found in HCI development: (1) a rigorous analysis of the nature of the data and how it will be used, and (2) a general method for sending data into functions for display on the user interface. The addition of two techniques like the above adds new tools to the engineering HCI toolkit and increases HCI designers' ability to meet the needs of engineers who examine large volumes of engineering data. | |||
| Empowering Young Adolescents to Choose the Healthy Lifestyle: A Persuasive Intervention Using Mobile Phones | | BIBAK | Full-Text | 117-126 | |
| Lies Kroes; Suleman Shahid | |||
| Overweight is one of the major health problems in the Netherlands. Young
adolescents with a lower socioeconomic background are especially vulnerable to
overweight. This study examines the potential of mobile applications to
influence the unhealthy behaviour of young adolescents. A mobile application is
proposed to assist in the prevention of overweight using persuasive technology.
The application encourages young adolescents to increase fruit consumption and
decrease snack consumption. Results of the evaluation show that participants
perceive the app as easy to use and useful. Overall, participants showed a more
positive attitude and self-efficacy regarding the consumption of fruit, and a
more negative attitude towards snacks, which is subsequently expected to
influence their behaviour in the long term. According to participants, social
influences generated by the app further contribute to this change in attitude
and behaviour. Keywords: Persuasive technology; overweight; behaviour change; attitude - social

| Every Project that involves Design in its process requires the gathering of
information related to the current contexto, the technologies involved and
concepts to be approached. In this research, the first step after the
delimitation of the scope of the project was to develop a profound analysis of
the related areas to Design. In accordance to this procedure, it became
possible to start understanding the relationship between different areas.
Telemedicine being the central issue of this research, it becomes necessary to
limit its connections with the other areas, such as Design. To begin with, it
is necessary to explain the topics of interest of the researchers: Design, HCI
(Human-Computer interaction) and ergonomics. From this point on, it could be
added the interest in areas such as collaborative learning and mobility, that
could influence the paths of the research. Moving forward, such concepts can be
explored. Keywords: Human Centered Design; Design; Telemedicine; Collaborative Learning;

| A Proposal of the New System Model for Nursing Skill Learning Based on Cognition and Technique | | BIBAK | Full-Text | 134-143 | |
| Yukie Majima; Yasuko Maekawa; Masato Soga; Masayuki Sakoda | |||
| It is necessary to acquire not only specialized knowledge but also
appropriate nursing skills in nursing education. In this paper, we propose an
e-learning system model to support a high level of technique learning, such as
"tacit knowledge" and "proficient art" in nursing skills, which have been
heretofore learned only from experience. This e-learning system enables
self-learning in addition to intellectual learning, thereby enhancing knowledge
of procedures and understanding of nursing skills. The results of evaluation
experiments showed that each system had learning effects. However,
simultaneously, they indicated the importance of the capability of
self-training with actual trial-and-error to acquire skills. For that reason,
adding "check point learning" to the already developed cognitive learning
support system as a new function, we made improvements to provide nursing
skills training covering detailed items. Based on this, we propose step-by-step
learning after completing learning in the cognitive domain through spiral
learning, which is the first step (from intellectual learning support to skill
learning support again to intellectual learning support), learners move on to
the second step (technique learning support) in a phased manner. We think that
other evaluation given by instructors by checking between the first and second
steps, as well as checking self-leaning, reduces the sense of loneliness, which
is a common pitfall an e-learning, and which provides satisfaction with
self-learning outcomes and a motivation for additional learning development. Keywords: Nursing skill; E-learning; Cognition; Tacit knowledge; Finger motion capture | |||

| Rangarajan Parthasarathy; Xiaowen Fang | |||
| The use of healthcare websites is gaining importance in the United States.
It is conceivable that when using healthcare websites, the users may not be in
a happy or euphoric emotional state, and would like to be comforted. In this
paper, we argue that using emotional interfaces in healthcare systems will
attract users, and motivate them to stay, participate and return. We suggest a
possible future state for emotional interfaces in healthcare systems. In this
context, we present a review of relevant theories and research studies from
Computer Science and Psychology, and a subjective ranking of some well-known
healthcare websites in the United States with respect to their hedonic and
emotional values. Lastly, we discuss our proposal for developing emotional
interfaces for healthcare websites. Keywords: Healthcare Websites; Hedonic Websites; Emotional Websites; Emotional

| Human Adequate Lighting in Optimal Healing Environments -- Measuring Non-visual Light Effects of a LED Light Source According to German Draft Pre-standard DIN SPEC 5031-100:2012 | | BIBAK | Full-Text | 163-172 | |
| Herbert Plischke; Christoph Schierz; Peyton Paulick; Niko Kohls | |||
| Exposing human beings to natural light has many empirically and
experimentally corroborated effects on health, well-being and quality of life.
One important effect is the entrainment of the human "master clock" to the 24h
rhythm of the solar day. In contrast, being surrounded by darkness during the
night increases blood levels of melatonin, the brain derived "sleep hormone",
and thus signaling other organs aside from the brain. However, in contrast to
earlier times, particularly in urban areas distinct periods of the day marked
by bright and dark light conditions are scarce, as modern lifestyle has changed
and artificial lighting is present in cities on a 24 hour basis. In addition to
the merely "visual" effects, light also exhibits non-visual, but biologically
relevant (time, spatial, quality and quantity dependent) effects, that are
mediated by specialized cells in the eye. These non-visual effects, such as the
suppression of melatonin during nighttime may potentially be regarded as a
severe risk factor to human health. Due to the discovery of the relationship of
light exposure and melatonin suppression, studies have been conducted to
evaluate which properties of light are most effective in suppressing melatonin.
In 2009 a first pre-standard for determining the non-visual effects of light mediated through the eye was established by the German Institute of Standardization (DIN). In this paper we describe, according to the standard, one approach to assess melatonin suppressing potential of light sources on the basis of mathematical algorithms that can be utilized as a conceptual platform for planning visual and non-visual effective lighting for optimal healing environments.

| According to F.P. Brooks, werewolves are the most terrifying of all monsters
because they are common people who are transformed into nightmares. Likewise,
nothing can be more concerning than having a semantic system that produces
inaccurate results due to unidentified problems in the ontology. Inaccurate
medical information can have catastrophic consequences. This paper will briefly
discuss some issues with existing biomedical ontologies. For instance, the
part-of and has-part dilemma may lead to alternative interpretations and
incompatibility among ontologies. Challenges concerning biomedical ontologies
can cause inadequate mappings between data elements and contents. Therefore,
causing major problems that can corrupt biomedical ontologies for large
multiscale and multidomain integration. Moreover, this can result in problems
with current methods used to manage biomedical ontology, and ambiguous and
inconsistent relation definitions between terms. Keywords: Meaningfulness and Satisfaction; Service Engineering; Universal Usability;

| Web Searching for Health Information: An Observational Study to Explore Users' Emotions | | BIBAK | Full-Text | 181-188 | |
| Pallavi Rao Gadahad; Yin-Leng Theng; Joanna Sin Sie Ching; Natalie Pang | |||
| To-date, most of the research concerning online health information search
has focused on how users search the Web and how they evaluate health websites.
Despite the concerns raised on the impact of online health information on
users, there is little research specifically exploring the problems users
encounter and emotions they exhibit during the search process. In this paper,
we address this gap by conducting an observational study to understand how
users search the Web for health information, the problems they encounter and
the emotions they express during the search process. Through eye-tracking,
think-aloud and interviews, we examined users' search process holistically.
Results showed that users exhibited various negative emotions during the search
process especially when there are perceived health risks. Highlighting the
theoretical and practical implications of this study, this paper makes
recommendations for future research to delve deeper into understanding users'
emotions during Web searching for health information. Keywords: Web Search; Online Health Information; Emotion | |||

| Experiences with Arthron for Live Surgery Transmission in Brazilian Telemedicine University Network | | BIBAK | Full-Text | 197-206 | |
| Tatiana A. Tavares; Gustavo H. M. B. Motta; Guido Souza Filho; Erick Mello | |||
| The increasing network bandwidth capacity and the diminishing costs of
related services have led to a rising number of applications in the field of
Information and Communication Technology. A special case is applications based
on video streaming. Telemedicine can be highlighted in some scenarios for
applying this technology, such as clinical sessions, second medical opinion,
interactive lessons or virtual conferences. These scenarios often imply a
dedicated transmission environment. A restriction in such solutions is the
inability to handle multiple video streams. Thus, this paper presents a
low-cost infrastructure for video collaboration in healthcare and based on open
technologies. The proposed infrastructure enables remote management of
simultaneous multiple streams. We also discuss results of experiments held in
the Lauro Wanderley Academic Hospital, Brazil. One of the results is the
contribution for teaching experiences, particularly by allowing students to
remotely regard surgical procedures and providing real-time interaction.
Finally, we present new prospects for using the developed technology on other
applications in Telemedicine and Telepresence. Keywords: New Technology and its Usefulness; eHealth and Telemedicine Systems | |||

| In the context of accelerated development of information technology and
knowledge-based economy, smart life comes near to us. In this paper, we would
talk about the design of intelligent public information service. We take the
project "Beijing Electronic Health Records" as cases to analyze the problems
encountered in our life, and we will analyze digitized resources and the
application in the city and clarify public information needs from the user's
perspective. On this basis, this paper will also include an in-depth study of
urban public information service design principles and methods, and conduct
cross-disciplinary research in information science, social sciences and design.
Finally, we conclude three main perspectives to design and evaluate the smart
public information service system: interfaces of technology-mediated mobile
terminals, process of information based on advanced technology such as Mobile
Cloud Computing, and a feedback mechanism to strengthen human interaction
accessibility in public information service system. Not only do the three
points maintain system performance, but also they play a significant part in
enhancing User Experience (UX) in public information service system. Keywords: Public Information Service; Interaction Design; User Experience | |||
| The Proposal of the Remote Consultation Service System Using the Outline Function for Consultation | | BIBAK | Full-Text | 216-225 | |
| Hiroshi Yajima; Takuto Gotoh | |||
| Remote welfare services for caregivers have recently been offered in
response to the recent increase in demand for care that has accompanied the
aging of society. However, due to the often extended periods of caregiving
involved, care consultations can sometimes lack cohesion unless information
about the early stages of care are available. In order to address this issue,
the whole history of communication between care experts and family members
should be structured and visualized when remote welfare services are provided.
We propose a form of remote consultation where care experts can offer coherent
and efficient consultations using all available information, such as up-to-date
information from "lifelogs" and past processes of care consultations obtained
from the use of all historically available information. Keywords: remote consultation; care; computer-mediated communication; care assistance | |||
| Design Guidelines for Audio Games | | BIBAK | Full-Text | 229-238 | |
| Franco Eusébio Garcia; Vânia Paula de Almeida Neris | |||
| This paper presents guidelines to aid on the design of audio games. Audio
games are games on which the user interface and game events use primarily
sounds instead of graphics to convey information to the player. Those games can
provide an accessible gaming experience to visually impaired players, usually
handicapped by conventional games. The presented guidelines resulted of
existing literature research on audio games design and implementation, of a
case study and of a user observation performed by the authors. The case study
analyzed how audio is used to create an accessible game on nine audio games
recommended for new players. The user observation consisted of a playtest on
which visually impaired users played an audio game, on which some interaction
problems were identified. The results of those three studies were analyzed and
compiled in 50 design guidelines. Keywords: audio games; accessibility; visual impairment; design; guidelines | |||

| Extreme Motion Based Interaction for Enhancing Mobile Game Experience | | BIBAK | Full-Text | 249-257 | |
| Youngwon Kim; Jong-gil Ahn; Gerard Jounghyun Kim | |||
| In this paper, we propose to enact interaction by "extreme" motion involving
multiple body parts and thereby maximize the whole body experience. By
detecting the relative movements among multiple body parts, rather than an
extended motion of just a single body part, the extreme motion can be contained
within the personal space (not to disturb others around). Such a scheme was
tested on a simple mobile game and compared to interfaces that were based on
conventional touch interface and absolute motion detection. Experimental
results showed that while incorporating extreme "relative" motion resulted in
higher level of excitement and user experience by involving more body parts,
the control performance significantly suffered (due to the head movements). Keywords: User Experience; Extreme motion; Whole Body Interaction; Motion Detection | |||

according to the display and controller. The research used 2D and 3D as gaming
display and joypad and Move as gaming controller. It examined the effects of
those variables on perceived characteristics, perceived interactivity,
presence, and discomfort. Sixty four participants joined the experiment and the
main findings are as follows: First, the interaction effect of the display and
controller was not significant for any of the variables. Second, the main
effect of the display was significant in the perceived characteristics of
clarity and materiality. Finally, the main effect of the controller was
significant in the perceived interactivity, spatial involvement, dynamic
immersion, and realistic immersion. Although the present research found
significant effects of those independent variables, a follow-up study is needed
to investigate why the interaction effects are not supported. Keywords: 3D; controller; discomfort; display; game; perceived characteristics;

| A Cross-Cultural Study of Playing Simple Economic Games Online with Humans and Virtual Humans | | BIBAK | Full-Text | 266-275 | |
| Elnaz Nouri; David Traum | |||
| We compare the simple online economic interactions between a human and a
multimodal communication agent (virtual human) to the findings of similar
simple interactions with other humans and those that were run in the
laboratory. We developed protocols and dialogue capabilities to support the
multi modal agent in playing two well-studied economic games (Ultimatum Game,
Dictator Game). We analyze the interactions based on the outcome and
self-reported values of possible factors involved in the decision making. We
compare these parameters across two games, and the two cultures of US and
India. Our results show that humans' interaction with a virtual human is
similar to when they are playing with another human and the majority of the
people choose to allocate about half of the stakes to the virtual human, just
as they would with another human. There are, however, some significant
differences between offer distributions and value reports for different
conditions (game, opponent, and culture of participant). Keywords: Culture; Values; Decision Making; Virtual Human; Economic Games;

| Best Practices for Using Enterprise Gamification to Engage Employees and Customers | | BIBA | Full-Text | 276-283 | |
| Marta Rauch | |||
| Enterprise gamification is one of the major human-computer interface trends of the 21st century. Using techniques borrowed from software games, gamification can be used to drive behavior in situations outside of games. As defined by Michael Wu, gamification "uses game attributes to drive gamelike behavior in a non-game context."[1] When implemented successfully, gamification can give enterprises an edge by increasing user motivation and achievement of goals. Gamification can also help enterprises engage employees and customers, and meet business needs. Given these benefits, it is no surprise that the move to enterprise gamification is accelerating. Enterprises of all sizes and in many industries are ramping up on products, communities, and processes based on gamification principles, and enterprise gamification is growing at an impressive rate. This rapid rate of implementation brings opportunities for enterprises that can implement gamification effectively. To adapt to this trend, professionals in the field of human-computer interaction must understand best practices, and develop expertise and skills in enterprise gamification. To meet this need, this paper looks at why enterprises benefit from gamification; provides selected examples of enterprise gamification; and lists best practices for gamification projects. | |||
| Gamifying Support | | BIBAK | Full-Text | 284-291 | |
| Anthony Chad Sampanes | |||
| When applied with care and consideration, gamification can have significant
positive effects on support. Utilizing gamification elements, such an
leaderboards, levels, badges, and rewards, within a community can help engage
customers and encourage them to generate support content. This allows them to
self-serve and more quickly resolve their issues. Internal support engineers
can also be motivated when exposed to a point system with appropriate
challenges, levels, and rewards. The result can increase overall job
satisfaction, increase engineer positivity, and lead to better customer
service. Keywords: Gamification; Support; Enterprise; Ticketing systems; Customer help;

| The Motivational GPS: Would a Rat Press a Lever to Get a Badge? | | BIBAK | Full-Text | 292-298 | |
| Kes Sampanthar | |||
| Gamification is a new industry that has blossomed around technologies that
incorporate Motivational Design. This is a game design method based on creating
truly engaging software that incites player motivations. There has been a lot
of new research into motivation over the last decade, but to understand what we
have learned about motivation we need to come back to the question about the
rat and the badge, which is drawn from Skinner's classic experiment. More
recent research shows that 'Wanting' is at the heart of what is considered
motivation and approach behavior, while 'Liking' is the feeling of euphoria
that is experienced when a challenge is overcome. Based on this research, we
describe an application of The Motivational GPS framework which uses the
metaphor of maps and directions related to 'Wanting' and 'Liking' to help
create design artifacts that can be used to create engaging software. Keywords: Interaction design; Human Motivation; Gamification; Game Design | |||
| Designing Serious Videogames through Concept Maps | | BIBAK | Full-Text | 299-308 | |
| Jaime Sánchez; Matías Espinoza | |||
| The purpose of this study was to present and evaluate a new technique
through the use of concept maps for the design of serious videogames using
Ejemovil Editor. This was accomplished by using a method to easily transform
concept maps into directed graphs, which are then used to generate the
videogame sequence and the interdependencies between the various elements. With
this tool teachers are able to define the storyline of the videogame,
incorporating the concepts that they want to teach in a structured way. To
these ends, an editor was created using this methodology that allows for the
construction of mobile videogames. Teachers that currently use concept maps
have evaluated the proposed methodology. Preliminary results show that the
proposed methodology for the design and creation of serious videogames for
education is appropriate, easy to use, generally accepted and understandable
for the end users. Keywords: Concept Maps; Serious Videogames; Videogames Editor; Videogames Design | |||

| Lynn Rampoldi-Hnilo; Michele Snyder | |||
| Gamification is becoming popular in enterprise applications due to benefits
such as motivating employees to work harder through team competition and
rewards. Mobile workers are a perfect audience for gamified applications as
they need to be connected to their teams and aware of important business goals.
Smartphones have specific characteristics that make them an ideal medium for
gamified applications. However, designing these types of applications correctly
is critical in determining their success. This paper will discuss gamification
in terms of mobile workers and their needs, smartphone characteristics, and
five mobile gamification design principles that help mobile workers stay
connected to the business goals at hand. Keywords: Gamification; Mobile; Smartphones; Design; Social Networking | |||

| Usability and playability of a game are two dimensions merging into each
other and affecting the experience. Within this paper we study the navigation
experiences of a small rider group playing an orientation game by means of
smartphones. The players are inexperienced in using smartphones and try to
reach the first game station. Studying their navigation process we learned how
the players adopted the game device, solved a navigation problem and entered
the game world. The case study illustrates three development stages of
navigational behavior of the rider group in the analyzed mobile game. Keywords: Mobile Game; Location-based Game; Play Experience; Evaluating Mobile Games;

| A New E-learning System Focusing on Emotional Aspect Using Biological Signals | | BIBAK | Full-Text | 343-350 | |
| Saromporn Charoenpit; Michiko Ohkura | |||
| E-learning is the computer and network-enabled transfer of skills and
knowledge. It is widely accepted that new technologies can make a big
difference in education. Although the advantages of e-learning over person to
person teaching are still under debate, the latter is considered to be superior
with respect to teaching effectiveness. One reasons for this advantage of human
expert tutors is their ability to deal with the emotional aspects of the
learner. In an e-learning system, emotions are important in the classroom. We
thus proposed a new e-learning system that focuses on affective aspects. Our
system equips sensors to measure biological signals and analyzes user emotions
for the improvement of the e-learning system's effectiveness. Keywords: E-learning; Emotions; Affective aspects; Biological signal | |||

| Refining Rules Learning Using Evolutionary PD | | BIBAK | Full-Text | 376-385 | |
| Afdallyna Harun; Steve Benford; Claire O'Malley; Nor Laila Md. Noor | |||
| Using glyphs to associate digital media with physical materials has great
potential to enhance learning. A key challenge, however, lies in enabling
children to author their own glyphs that integrate well with their drawings.
One possible solution lies in the d-touch system which uses a topological
approach to structuring glyphs. Through a series of Participatory Design
studies, we have explored how children can be supported in creating their own
d-touch glyphs. Main highlights from our findings indicate that it is difficult
for children to create glyphs following only written rules. A structured
diagrammatic approach is then introduced in which colour-coded hierarchy
diagrams support a mapping between their drawings and the underlying rules. We
found this has significantly improved their drawing attempts. The paper then
concludes with a potential to integrate the approach into more sophisticated
learning experience. Keywords: Drawing rules; visual diagrams; d-touch glyphs | |||

| Examining the Role of Contextual Exercises and Adaptive Expertise on CAD Model Creation Procedures | | BIBAK | Full-Text | 408-417 | |
| Michael D. Johnson; Elif Ozturk; Lauralee Valverde; Bugrahan Yalvac; Xiaobo Peng | |||
| As computer-aided design (CAD) tools become more integral in the product
commercialization process, ensuring that students have efficient and innovative
expertise necessary to adapt becomes more important. This work examines the
role of adaptive expertise on CAD modeling behavior and the effect of
contextual modeling exercises on the manifestation of behaviors associated with
adaptive expertise in a population of student participants. A methodology
comprising multiple data elicitation tools is used to examine these
relationships; these tools include: survey data, model screen capture data
analysis, and interviews. Results show that participants engaged in contextual
exercises spent more of their modeling time engaged in actual modeling
activities as opposed to planning when compared to a control group. Limited
statistical support is provided for the role of contextual exercises leading to
the manifestation of behaviors associated with adaptive expertise. The amount
of time spent engaged in actual modeling is positively correlated with the
adaptive expertise behaviors identified in the interviews. Keywords: Adaptive Expertise; CAD; Evaluation Methods and Techniques; Modeling

| Personality and Emotion as Determinants of the Learning Experience: How Affective Behavior Interacts with Various Components of the Learning Process | | BIBAK | Full-Text | 418-427 | |
| Zacharias Lekkas; Panagiotis Germanakos; Nikos Tsianos; Constantinos Mourlas; George Samaras | |||
| The aim of the present study is to develop a model that grasps the
complexity of the concepts of personality and affect in a web-based learning
environment. Furthermore, it presents the implications that these theoretical
and empirical representations can have in an experimental setting. We are
investigating the connection between personality factors, emotion regulation
and cognitive processing tasks, decision making and problem solving styles.
Decision-making and problem solving are cognitive processes where the outcome
is a choice between alternatives. They are both an indirect way to make
inferences to a person's learning pattern since learning includes continuous
decision making and problem resolution. By implementing our model in the design
of a web-based learning personalized setting, we provide evidence that behavior
is altered by affective elements in decision making and problem solving
routines as is performance in cognitive processing tasks. Keywords: personality; affect; emotion; learning | |||

| A Teacher Model to Speed Up the Process of Building Courses | | BIBA | Full-Text | 434-443 | |
| Carla Limongelli; Matteo Lombardi; Alessandro Marani; Filippo Sciarrone | |||
| Building a new course is a complex task for teachers: the entire process requires different steps, starting with the concept map building and ending with the delivery of the learning objects to students through a learning management system. Teachers have to spend a lot of time to build or to retrieve the right learning material from local databases or from specialized repositories on the web. Consequently, having a system supporting this phase is a very important challenge, considering that each teacher expresses her own pedagogy as well. Here we propose a novel Teacher Model that helps teachers to build new courses effectively. The model is based both on a didactic semantic network containing concepts and learning material and on Teaching Styles as proposed in the literature by Grasha. This framework gives teachers the possibility to share their teaching experience as well. A first experimentation of the system gives positive results. | |||
| Development of Push-Based English Words Learning System by Using E-Mail Service | | BIBA | Full-Text | 444-453 | |
| Shimpei Matsumoto; Masanori Akiyoshi; Tomoko Kashima | |||
| At present, common e-Learning systems have been designed for positive learners whose learning habits are already established to some degree. To assist students other than the positive learners, most of who has more difficulty in learning with the usual e-Learning systems, this paper focuses on a new type of e-Learning system called "push-based e-Learning". The push-based e-Learning is for learners who cannot establish study habits or take an active part in learning, and be an essential tool for supporting self-study continuity. This study realizes push service by e-mail technology of cell-phone. The system, used in conjunction with an interactive e-mail service through cell-phones, allows users to automatically receive up to some exercise e-mails a day. For our system, this paper implemented COCET 3300, a corpus of English words, and made a trial operation of our system with several university students for training English vocabulary. This paper firstly shows the detail of system configuration, and then evaluates our implementation of push-based e-Learning with the result of the trial operation. From the trial operation, the effectiveness of our system was shown by questionnaire while the result was on the students' subjective viewpoint. | |||

| This paper reports on e-learning as a transformational educational tool
amongst Communication Science students at Unisa. The study targeted executive
members of the Communication Science Association (COMSA) which consists of ten
members and Unisa Radio employees which comprise 200 Communication Science
students. A survey research design was used whereby questionnaires were
administered to all COMSA executives and 50% of Unisa Radio student employees
who were chosen using simple random sampling. Data was analysed through
thematic categorisation and tabulation and the findings were presented
descriptively. An examination of data indicates that students do not actively
engage in e-learning. They use myUnisa for basic educational needs and not for
the purpose that myUnisa was intended which is to bridge transactional distance
in order to ensure increased engagement amongst all stakeholders. Unisa needs
to examine its current e-learning policies against the backdrop of the society

manifestation of strong voices calling for learning in natural contexts. The
study was based on a sequence of inquiry-based mobile learning activities
within the domain of natural sciences and mathematics education. We questioned
the effects of collaborative scaffolding, and the effects scaffolding provided
by technology have on learning and performance. Based on a quantitative
interaction analysis, findings suggest that low-achievement students benefit
from inquiry-based mobile activities; that the use of mobile technologies bring
multiple effects on students' learning, both positive and negative, and that
the roles of teachers remains as crucial as before the introduction of learning

| This paper examines two independent multimedia distribution systems in terms
of user's impression and the download time on the basis of the two experiments
which were carried out in English teaching settings in Japan. The two are the
podcasting system and the mobile-based system. The results of the two studies
indicated that the students feel that mobiles are more friendly and easy to
operate. Although it takes them longer time to download digital materials from
the server, they do not feel so much frustrated or irritated for being delayed
to a certain degree. These implications imply the future possibility for
blended-instruction model of foreign language teaching in Japan. Keywords: e-learning system; podcasting; mobile device; second language acquisition | |||
| Recommendation of Collaborative Activities in E-learning Environments | | BIBAK | Full-Text | 484-492 | |
| Pierpaola Di Bitonto; Maria Laterza; Teresa Roselli; Veronica Rossano | |||
| In distance education environments, collaborative activities such as wikis,
forums and chats play an important role in the e-learning experience because
they promote communication among students and so allow cooperative learning
settings to be implemented. Nevertheless, it could be difficult for learners to
pick out the most interesting and appropriate collaborative activities to meet
their learning needs. Recommender systems integrated in e-learning platforms
are usually used mainly to help learners choose teaching resources, but they
can also be useful to suggest the collaborative activities that best fit their
learning objectives from a pedagogical point of view. In this context, the
paper presents a recommendation approach able to suggest collaborative
activities such as forums, chats, wikis and blogs, that combines dynamic
clustering and prediction calculus on the basis of the learners' profiles and
needs. Keywords: Recommender system; collaborative learning; dynamic clustering | |||

| We have developed the TERAKOYA learning system, which helps students study
actively anywhere on a local area network (LAN) linked to multipoint remote
users. However, if many students frequently sent their questions to the
teacher, it is very difficult to correspond to quickly answer that for the
teacher. In addition, the teacher hardly clarifies how much each student
understood because he cannot watch students' face and reaction. This paper
discusses the graphical user interface (GUI) system that is used a little
ingenuity to prioritize students' screens through variably changing the GUI
interface on the teacher's PC. The aspect of window that was displayed as
thumbnails of the students' PC screen was zoomed dynamically each thumbnail by
their understanding level. By sorting out their priorities on the teacher's PC
screen, the teacher can timely observe the students' work and support their
thinking process. Keywords: GUI; Interactive system; Advanced Educational Environment; Ubiquitous

| This paper presents WheelSense, a system for non-distracting and natural
interaction with the In-Vehicle Information and communication System (IVIS).
WheelSense embeds pressure sensors in the steering wheel in order to detect
tangible gestures that the driver can perform on its surface. In this
application, the driver can interact by means of four gestures that have been
designed to allow the execution of secondary tasks without leaving the hands
from the steering wheel. Thus, the proposed interface aims at minimizing the
distraction of the driver from the primary task. Eight users tested the
proposed system in an evaluation composed of three phases: gesture recognition
test, gesture recognition test while driving in a simulated environment and
usability questionnaire. The results show that the accuracy rate is 87% and 82%
while driving. The system usability scale scored 84 points out of 100. Keywords: Tangible gestures; smart steering wheel; in-vehicle user interface; in-car

| This paper presents a solution to the problem of speeding in male young
drivers. This paper outlines the design of a persuasive mobile application that
aims at reducing speeding behavior by providing various incentives. The
application targets both weak and strong habit drivers between the age of 18
and 26. Early results show an overall acceptance of the application, mainly due
to its unique rewarding mechanism, and its ability to demonstrate the actual
speeding behavior with major impact on safety, fuel costs, environment, and
possible fine costs. Results further indicate a behavior change for weak habit
drivers and attitude change for strong habit drivers. Keywords: Speeding behavior; persuasive technology; mobile application; speeding

| Auditory and Head-Up Displays in Vehicles | | BIBAK | Full-Text | 551-560 | |
| Christina Dicke; Grega Jakus; Jaka Sodnik | |||
| The aim of the user study presented in this paper was to investigate the
efficiency of single and multimodal user interfaces for in-vehicle control and
information systems and their impact on driving safety. A windshield projection
(HUD) of a hierarchical list-based visual menu was compared to an auditory
representation of the same menu and to a combination of both representations.
In the user study 30 participants were observed while operating a driving
simulator and simultaneously solving tasks of different complexity with the
three interfaces. The variables measured in the user study were task completion
times, driving performance and the perceived workload. Our study shows that the
single modality auditory interface is the least efficient representation of the
menu; the multimodal audio-visual interface, however, shows a strong tendency
to be superior to both the auditory and visual single modality interfaces with
regards to driver distraction and efficiency. Keywords: Human-computer interaction; auditory interface; head-up display; car

drivers. We have presented an architecture that adopts context awareness and
Bump location broadcasting to detect and save bumps locations. This system uses
motion sensor to get the readings of the bump then we classify it using Dynamic
Time Wrapping, Hidden Markov Model and Neural Network. We keep records for the
bump location through tracking its geographic position. We developed a system
that alarms the driver within appropriate profiled distance for bump
occurrence. We conducted two experiments for testing the system in a street
modeled architect with different kinds of bumps and potholes. The other
experiment was on real street bumps. The results show that the system can
detect bumps and potholes with reasonably accepted accuracy. Keywords: Context awareness; Location awareness; Pattern Recognition | |||
| Emotion and Emotion Regulation Considerations for Speech-Based In-Vehicle Interfaces | | BIBAK | Full-Text | 571-577 | |

| Speech and dialogue systems have been used in a variety of domains, from
acting as human operators, to assisting those who have difficulties using other
modalities, and more recently facilitating smartphone input. Speech has been
more readily adopted by in-vehicle speech systems as the safest way to both
communicate to the driver and to have the driver provide input to the system.
Much of the work on speech dialogue systems has focused on the cognitive
aspects of speech interfaces by evaluating different information architectures,
e.g. [1], or comparing mixed modality interfaces, e.g., [2]. This paper argues
that advanced speech-based interfaces will have the need and opportunity to be
emotionally responsive. Keywords: emotion; emotion regulation; speech dialogue systems; in-car interfaces | |||
| Adaptations in Driving Efficiency with Electric Vehicles | | BIBAK | Full-Text | 578-585 | |
| Magnus Helmbrecht; Klaus Bengler; Roman Vilimek | |||
| The results of previous MINI E field trials provided initial indications
that driving electric vehicles (EV) leads to adaptations in driving behavior
and might increase driving efficiency. This paper presents the methodologies to
measure changes in driver characteristics by logging velocity, acceleration,
and cruising range, on smartphones. In this experiment, 25 MINI E were provided
as electric test vehicles for a diversified spectrum of subjects consisting of
private and corporate customers. The field trial included both longitudinal and
transverse components in order to assess long-term and situation specific
changes. Participants operated both combustive and electric vehicles. Driving
dynamics data from these vehicles was collected over a six month period time.
Additionally, these same participants were required to perform a 2 hour drive,
which served as a comparison drive, three times over the period of EV usage.
The frequency of intermittent usage of combustion vehicles was captured by
logbooks. Keywords: Electric Vehicle; Driving Behavior; Field Trial; MINI E | |||
| In-Car Information Systems: Matching and Mismatching Personality of Driver with Personality of Car Voice | | BIBAK | Full-Text | 586-595 | |
| Ing-Marie Jonsson; Nils Dahlbäck | |||
| Personality has a huge effect on how we communicate and interact with
others. This study investigates how dominant/submissive personality match and
mismatch between driver and voice of the in-vehicle system affects performance
and attitude. The study was conducted with a total of 40 participants at Oxford
Brookes University in the UK. Data show that drivers accurately discern the
personality of the car voice, and that car voice personality affects drivers'
performance. The dominant car voice results in drivers following instructions
better regardless of driver personality. The matched conditions showed 2 -3
times better driving performance than the mismatched conditions. Drivers with
the submissive voice in the car felt significantly less at-ease and content
after driving than drivers with the dominant voice. Design implications of
in-vehicle systems are discussed. Keywords: In-car System; Driving Simulator; Driving Performance; Speech system;

| Subjective Ratings in an Ergonomic Engineering Process Using the Example of an In-Vehicle Information System | | BIBAK | Full-Text | 596-605 | |
| Michael Krause; Klaus Bengler | |||
| The engineering process for a traffic light assistant system on a smartphone
for use while driving as an In-Vehicle Information System (IVIS) was
accompanied by assessment of subjective usability ratings using questionnaires,
such as the System Usability Scale (SUS), AttrakDiff2 and NASA-TLX. The results
during the development process are presented and discussed.
The SUS was an easy to apply and fast instrument for the project. Nevertheless, caution should be taken when a high percentage of users are repeatedly involved in examining the same system, as this will likely increase the SUS score.

| This research aimed to investigate and explore expert user interface design
principle in adaptive user interface of in-vehicle full voiced-based interface.
In this study, 3 stages of driving simulation experiments were established. The
voice-based interface called Talking Car novice interface has been designed
before. Through driving simulation experiments, subjects' behavior and response
data when using voice-based interface were collected and analyzed. According to
the result, the length of speech by Talking Car novice interface would be
adjusted to fulfill expert users' requirements, and then switched to Talking
Car expert interface. After that, a driving simulation experiment is conducted
to verify the usability of the adapted interface as well as the implications on
operation efficiency and traffic safety. Keywords: in-vehicle full voice-based interface; Talking Car; driving simulation;

| The Timeframe of Adaptation to Electric Vehicle Range | | BIBAK | Full-Text | 612-620 | |
| Stefan Pichelmann; Thomas Franke; Josef F. Krems | |||
| We explored how people learn to cope with the limited range of electric
vehicles (EVs), and examined the relationship between personality traits and
the amount of practice needed to achieve a maximum available range. Data from
56 participants who leased an EV in a 6-month field study were analyzed. The
amount of practice needed until a participant achieved his maximum available
range was assessed with four variables computed from data logger recordings:
the amount of time, days, and distance the user drove the EV and the amount of
days the user owned the EV. All four variables correlated strongly with each
other (r ≥ .75). The results showed that an average person needs
approximately three months to complete adaptation to EV range and that speedy
driving style, low need for cognition, high impulsivity, and high internal
control beliefs are related to a longer adaptation timeframe. Keywords: adaptation; electric vehicle; range; practice; need for cognition; driving

| An electric vehicle (EV) is more than just a car with an electric engine. It
implies a major shift in everyday experience. Charging the vehicle at home,
thinking about where this energy comes from, dealing with limited range or
driving a silent vehicle without engine noise are only some aspects of a
completely new ecosystem for an electric vehicle owner. Of course, EVs will
only succeed in the mass market if they meet customers' expectations. With the
decision to step into this unknown terrain, the BMW Group gathered data in
field trials with pilot customers of the MINI E and BMW ActiveE. The field
trials discovered that everyday driving does not differ significantly from
conventional vehicles in the same segment. About 90% of intended trips can be
realized, showing the gap that needs to be closed is manageable. In order to
close it, BMW will offer innovative mobility services and charging solutions. Keywords: Electric Vehicle; MINI E; BMW ActiveE; field trial; user study | |||
| Single-Handed Driving System with Kinect | | BIBAK | Full-Text | 631-639 | |
| Jae Pyo Son; Arcot Sowmya | |||
| This paper proposes a Kinect-based system that can help people who have
difficulties with moving one of their arms, to drive and control the vehicles
with only one hand. The advantage of the system is that only the user's hands
need to be visible, so that users can use the system while seated. Experiments
to measure system performance have shown reasonable accuracy. This system can
be broadly applied to any wheeled electronic vehicles such as an electronic
wheelchair, robot or car in future. Keywords: Assistive Technology; Kinect; Human-Computer Interaction; Hand Tracking;

| Mobile App Support for Electric Vehicle Drivers: A Review of Today's Marketplace and Future Directions | | BIBAK | Full-Text | 640-646 | |

| Mobile device applications (apps) are becoming an important source of
information, control, and motivation for EV drivers. Here we review the current
ecosystem of mobile applications that are available for EV drivers and
consumers and find that apps are available in six basic categories: purchase
decisions, vehicle dashboards, charging availability and payment, smart grid
interaction, route planning, and driver competitions. The current range of the
EV-specific mobile marketplace extends from pre-sale consumer information,
charging information and control, and EV specific navigation features among
other services. However, the market is highly fragmented, with applications
providing niche information, and using various methodologies. In addition, we
find that the barriers to more useful apps are a lack of vehicle and charger
APIs (application programming interfaces), lack of data availability,
reliability, format and types, and proprietary payment and billing methods. We
conclude that mobile applications for EVs are a growing market that provide
important direct benefits as well as ancillary services to EV owners, although
the lack of uniformity and standards between both vehicle and charger systems
is a serious barrier to the broader use of mobile applications for EVs. Keywords: Electric Vehicles; Mobile Apps; Energy Feedbacks | |||

| According to the AAA Foundation for Traffic Safety, driver inattention is a
major contributor to highway crashes. Above all, driver distraction is an
important factor. As a result, many studies have been performed on it. We also
performed experiments on candidates for biological indexes. In this paper, we
employed new biological signals (eye tracking). Then, we performed an
experiment to find new candidates for biological indexes. We obtained new
knowledge from the result of that experiment. Keywords: Driver distraction; Biological signal | |||
| Ergonomics Design with Novice Elicitation on an Auditory-Only In-Vehicle Speech System | | BIBAK | Full-Text | 654-660 | |
| Ming-Hsuan Wei; Sheue-Ling Hwang; Hsin-Chang Chang; Jian-Yung Hung; Chih-Chung Kuo | |||
| This research is aimed to design an auditory-only in-vehicle speech system,
named as Talking Car Novice Mode, and provide with elicitation that even a
novice can easily handle. In this study, 19 participants were asked to use
radio and music functions in two kinds of in-vehicle speech systems, the
original Talking Car and Talking Car Novice Mode, while driving through a
virtual world. Data of secondary task performance, the amount of time spent on
tasks and the times of calling help function were recorded by a camera. The
annoyed score of sentences, NASA-TLX questionnaire and subjective questionnaire
were completed after the test. The result indicated that there was no
significant difference between driving with and without tasks on either the
reaction time of slamming the brake or the times user call for help. Besides,
the learning curve of Talking Car Novice Mode is steep and ensures that Talking
Car Novice Mode provides enough elicitation to novices. Hence, the Talking Car
Novice Mode is expected to be friendlier and safer than original Talking Car
in-vehicle speech system for a novice user. Keywords: ergonomics design; Talking Car Novice Mode; elicited design; voice user
